### 2.3 Set Up VNC Connection Credentials
Before making a connection, you need to set up your VNC connection credentials. These typically include the device's IP address, port number, username, and password. Ensure these credentials are accurate to successfully establish a VNC connection and securely transfer files.

By completing the above preparations, you can ensure that using VNC Viewer for file transfer avoids common issues, enhancing work efficiency. Next, we will continue to discuss how to establish a VNC connection.

# 3. Establishing a VNC Connection

In this chapter, we will introduce how to use VNC Viewer to establish a connection with a target device for file transfer operations.

#### 3.1 How to Create a New Connection in VNC Viewer
First, open the VNC Viewer application. On the VNC Viewer main interface, you will find a "New Connection" or "新建连接" button. Click it to create a new connection configuration. Then, you need to input the target device's address, which could be the target device's IP address or hostname.
